【Abstract】 Objective To explore the surgical treatment of the primary retroperitoneal tumor (PRT). Methods A retrospective clinical data analysis was made on the 59 cases of PRT who underwent operation. Results 59 cases were diagnosed by operation and pathologic examination.In 41 cases of malignancyt ( 69.49%),complete resection, partial resection, surgical exploration and biopsy were performed on 15 cases (36.6%), 8 cases (19.5%) and 18 case (43.9%) , respectively. The 3- and 5-year survival rates of maligment PRT with total resection were 53.3% and 26.7%,and with partial resection were 19.23% and 7.69% respectively.In 18 cases of benign tumor (30.5%),complete resection, partial resection, surgical exploration and biopsy were performed on 14 cases (77.8%), 3cases (16.7%) and 1case ( 5.6%) , respectively. The 3- and 5-year survival rates of benign PRT with total resection were 92.86% and 85.7%,and with non-completely resection were 75.0% and 50.0%, respectively. Conclusions Operation is the main treatment of PRT. Early diagnosis and radical resection are the keys in improving the prognosis of PRT.更多还原
